ELECTRIC-LIGHTING APPARATUS FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 784,071, dated March 7, 1905.

Application filed April 9, 1904. Serial No. 202,378.

To all mil/011?, it may concern:

, Be it known that we, WILLARD F. RICH.- ARDS, residing at Buffalo, and I/VILLTAM A. TURBAYNE, residing at Lancaster, in the county of Erie and State of New York, citizens of the United States, have invented new and useful Improvements in Electric-Lighting Apparatus for Railway-Cars, of which the following is a specification.

This invention relates to apparatus employed in electric systems of distribution, such as the car-lighting and power system disclosed in United States Letters Patent of \Villiam A. Turbayne, No. 757,695, dated April 19, 1904:, and more particularly to a supporting-frame for a portion of the apparatus including a dynamo, the motor which drives the same, and a switch which is operated by the motor.

The object of the invention is to provide a containing frame of simple, strong, and desirable construction for supporting said several devices in a compact convenient relation and which enables the ready assembling of the parts for installing the apparatus and detachment thereof for making repairs and replacing worn parts.

In the accompanying drawings, consisting of two sheets, Figure is a vertical sectional elevation of an apparatus having a frame embodying the invention. Fig. 2 is a plan view thereof, partly in section. Fig. 3 is a View thereof, one-half in end elevation and one-half in vertical section, omitting the switch. Fig. 4 is a sectional elevation, on an enlarged scale, in line 4 4, Fig. 1, of one of the bearing-standards. Fig. 5 is a fragmentary section, on an enlarged scale, of one of the armature-shaft bearings, showing the 4o cap detached. Fig. 6 is a section of the bearing-standard shown in Fig. 4, the wormwheel being removed.

I Like letters of reference refer to like parts in the several figures.

A represents a base or stand which is preferably in the form of a hollow casting of generally-rectangular shape, having a substantially flat upper face on which the dynamo B and motor B for driving the same are supported. The armatures C C of the dynamo and motor are secured upon a common armature-shaft D, the end portions of which are journaled in. bearing-standards E E. The latter are bolted to the base A (see Fig. 3) and are preferably in the form of hollow housings and are provided with tops or caps c, which are bolted or otherwise removably secured to the standards.

F represents bearing-sleeves or bushings for the armature-shaft, one supported in each of the hollow l' earing-standards in a saddle-block or cross-piece f of the hollow l)earing-standard, in which it is retained by a cross piece or bar f on the removable cap of the standard, having a semicircular seat to surround the upper portion of the bearingsleeve or bushing. The bearing-sleeves or bushings, mounted as described, provide sellalining bearings for the armature-shaft.

The dynamo and motor are of that kind having laminated field-magnets composed of parallel thin metal plates g, bound or clamped together.

H represents clamping-plates or frames of substantially the same shape as and arranged on opposite sides of the field-plates of both the dynamo and motor. The fieldplates, together with their clamping-plates, are firmly clamped together by horizontal rods or bolts I, located at opposite sides of and parallel with the armature-shaft and which pass through holes in the sides of the field-plates and clamping-plates. The clamping belts or rods I are of greatest diameter at their middle portions to form shoulders i, against which the inner clamping-plates abut. The field and clamping plates are clamped between said shoulders and nuts 0' screwed on threaded portions i of the clamping belts or rods outside of and adjacent to the outer clamping-plates or frames. The

reduced opposite end portions of the clamping belts or rods pass through perforated lugs 7: on the bearing-standards, in which they are secured by nuts 7r, screwed on their threaded ends. The field and clamping plates are securely clamped onthe rods or bolts I and are rigidly tied to the bearingstandards by the clamping rods or bolts, thus producing a very stable and strong though light frame. The clamping-plates H are further secured to the base by belts orscrews Z, which are inserted in registering holes in the base and flanges on the bottoms of the clamping-plates after the latter and the field-plates have been clamped in place on the clamping bolts or rods.

M represents a switch the movable member m of which is moved in opposite directions to make and break contact with the stationary members of the switch by a rod on, which is connected to the movable switch member and is reciprocated by the armatureshaft of the dynamo and motor through suitable gearing hereinafter described. This switch, which is fully described in our application for United States Letters Patent, filed of even date herewith, Serial No. 202,374, is supported by a switch board or plate N, which rests upon the tops of the dynamo and motor field-magnets and is secured to the upper ends of vertical columns or bolts 12, which are screwed into threaded holes in the side portions of the bearing-standards for the armature-shaft or are otherwise secured to the standards or base A. The switch board or plate is firmly and rigidly supported above the dynamo and motor and can be readily detached from the vertical supporting-bolts when necessary.

The reciprocating operating-rod m for the switch is preferably connected by a link 0 to the upper end of a lever P, which is secured at its lower end to a rock-shaft p, j ournaled in bearing-lugs p on the removable cap for the bearing-standard E. The rock-shaft has an arm p which extends down at one side of the bearing-standard and constitutes, in effect, a depending arm of the lever P.

Q is a crank-shaft which is j ournaled in the bearing-standard E transversely of the armature-shaft and is provided at its outer end with a crank or wrist pin g, which works in an elongated slot in the depending arm of the operating-lever P for the switch. The crank-shaft is driven from the armatureshaft by a worm-gearing consisting of a worm r, detachably secured to the adjacent end of the armature-shaft, and a worm-wheel r, secured to the crank-shaft and meshing with the worm. The crank-shaft preferably bears the bearing-standard E and at its other end in a hole in a removable bearing-plate s, Fig. 4, which is preferably circular and is removably secured by screws or the like 3 over a circular hole 8 Fig. 6, in the adjacent side of the bearing-staiulard, which hole is of larger diameter than the worm-wheel. By loosening and removing the bearing-plate s for the crank-shaft the latter, with the worm-wheel secured thereon, can be slipped endwise out of the bearing-standard, it being necessary only to lift the adjacent end of the arm atureshaft sufficiently to permit the teeth. of the worm-wheel to disengage the teeth of the worm. The worm driving gear for the switch is inelosed and protected in the hollow bearing-standard, and the latter provides containing chambers for oil or grease for the worm-gearing and journal of the armature-shaft to run in. The removable caps for the bearing-stalldards are provided with lubricant-filling holes, closed by screw-plugs or other suitable closures t, which enable the introduction of lubricant into the lubricantchambers without removing the bearingcaps.

U U represent, respectively, the commutators, and Qt a the brushes cooperating therewith, for the dynamo and motor. Each pair of brushes is mounted on arms projecting from a supporting-ring 11. which surrounds a circular boss on the adjacent bearing-standard, to which it is secured by bolts or screws it, Fig. 2, passing through holes in arms on the supporting-ring. These fea tures form no part of the present invention and are not herein described in detail.

The dynamo B is employed, as in said patented system, as fully explained in the patent, to excite the field-winding of the main generator and is driven by the motor B and the switch is used, as fully explained in said application Serial No. 202,374, for regulating the voltage of the work-circuit by successively introducing eounter-electromotiveforce cells or other resistance into and withdrawing the same from the system.
